FOUNTAIN PEN.

Original Io. 1,448,524, dated February 27, 1923, Serial No. 557,558,filed May 1, 1922. Application for reissue fled February 23, 1924.Serial No. 694,458.

My invention relates to fountain pens, primarily to that class commonlyknown as self fillers. The invention comprehended in the drawings andspecification is applied to the I so called all metal pen, but is notlimited to pens of that particular construction.- a

The principal object of the invention herein described is to'providemeans whereby a lever which co-operates with the interior mechanism forcompressing an ink sack for filling the fountainpen is fulcrumed in alongitudinally extending slot in the barrel. Heretofore it has beennecessary in all metal pen construction to fulcrum-the lever in the slotthrough a medium of a shell having a saddle thereon being slipped intothe barrel. The lever is then hooked on to the saddle as is described inpending application of John C. Wahl, filed April 2, 1921, Serial No.

457,873. The other means for fulcruming the lever in the slot is tointurn the edges of the slot and form flanges; the lever is thenintroduced into the slot and a pin is inserted-through aligned aperturesin the lever and barrel flanges. This method is I shown in my co-pendingapplication dated April 10, 1922, Serial No. 551,121. Both of theaforementioned methods of aifixing a lever in the slot in an all metalpen are unsatisfactory; the first because the shell takes up .too muchspace within the barrel of the pen; the second because ofthe difiicultyof assembling the lever in the slot. My present invention obviates thedifliculties present in both of the other methods of assembly of thelever in the slot.

Other objects will appear hereinafter as the specification proceeds.

The invention consists in the combination and arrangements of partshereinafter described and claimed, and will be best understood byreference to the accompanying drawings forming a part of thisspecification, and in which,

Fig. 8 is a sideview of the modification shown in Fig. 7

The numeral 1 indicates a barrel having a longitudinal extending slot 2punched therein. .During the process of punching out the slot 2, flanges3 and 4 are formed and depressed into the chamber within the barrel 1.The lever end of the barrel 1 is enclosed by the tassie 1, which is spuntherein. The upper end of the barrel is slightly beveled and has threads5 rolled thereon. The usual pen section 6 having an ink sack 7attachedthereto is inserted into the upper end of the barrel and is heldtherein by frictional engagement with internal projections formed by therolling of the threads 5. A cap 8 having an internal rubber shell 9 forenclosingthe nib of the pen section'is provided. A clip 10 is aflixed toto the cap in a manner shown in Patent No. 1,279,186 granted to John G.Wahl and Wm. H. Odlum, dated September 17, 1918. Threads 11 are providedwithin the lower extremity of the cap which are adapted to engage therolled threads 5 when the capis introduced over the pen section.

A lever 12 having locking flanges 13 at its outermost extremity whichco-operate with the flanges 3 for locking the lever in closed positionis provided. In the forming of the lever, outstanding wings 14 areformed at its lowermost extremity, said outstanding wings 14 beingadapted to engage under flanges 15 formed on the presser bar 16, the

presser bar being mounted interiorly of'the barrel directly beneath thelongitudinal extending slot. The flanges 4 are provided for the purposeof fulcruming the lever within the slot, said flanges having alignedapertures therein, said aligned apertures being in alignment withcorresponding apertures punched in the edge of the lever intermediate ofits ends. Mounted between the flanges, formed in the stamping out of thelever 12, is a piano wire spring of small diameter having its ends bentoutwardly as illustrated at 17 in Fig. 4. The spring is com ressed whenit is introduced between the anges of the presser bar, thepresser bar isthen introduced into the slot and the apertures in the flanges 4 and inthepresser bar 12 are aligned, whereupon the spring 1s slipped downuntil the lateral extending ends engage in the apertures, whereupon thespring expands and the ends 'of said spring snap into engagement of the.apertures in the flanges 4, thus fulcrumingthe lever in the slot. Whenit is foundnecessary to disassemble the lever the operation is asfollows:

A pin is introduced under the top edge of the spring and it (the spring)is forced outward from its frictional engagement with the flanges of thepresser bar. A pair of pliers is then applied to the spring and 1t iscompressed until the lateral extending ends are released from theapertures .in the flanges 4, whereupon the presser bar is withdrawn fromthe slot. The provision of the spring or holding element 17 permits easeof assembly and ready accessibility of the lever and its corres ondingparts. This has not been aocompl' ed as heretofore explained in otherall metal pens having the lever type of filling device. For that reasonthis lnvention was conceived.

The drawings show other modifications of the spring holding element. Forinstance, in Fi 6 the holding element is shown with in entations 18therein. These indentations are for the .purpose of permitting theinsertion of a tool between the sides of the flanges for compressing thespring. When the spring is compressed, the indented parts will ride overand under one another, the spring will be compressed and the lateralextending ends will be withdrawn from the a ertures in the flanges 4. InFig. 7 I have s own a holding element formed from a flat spring havinground projections 19 extending therefrom; the assembly of the leverhaving this form of holding element therein is the same as describedheretofore.

It is not thought necessary to describe those parts of the fountain penshown that are not to be claimed in this application, as they arespecifically described in my conding application dated April 10, 1922,

ial No. 551,121.

While I have illustrated and described the preferred form ofconstruction for carrying my invent-ion into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set'forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.
